objective c - iOS - How to restrict application installs on different devices for a specific user -


i working on in-house enterprise application. idea restrict specific user install/run application on x number of devices.

what best possible way that? way can think of using kind of certificates ( ones testflight or hockeyapp installs uniquely identify device , communicate server ). have no idea how that?

so how can achieve this?

edit

to explain question further, following sample scenario: '

"i have video streaming application, , want restrict user use login upto 5 different devices. when try login on 6th device. login fail."

i want achieve functionality. cannot generate random guid , save along user details on server. if user un-install application on same device , installs again. there no change device have same guid , considers server new device. hope scenario clear.

you can using default ad-hoc distribution. udid's devices, add them apple developer portal, , generate new provisioning file once you've gotten devices want. testflight isn't needed, can on own quite easily.
